Every iMessage is encrypted on your device and not decrypted until it reaches the recipient, so your carrier wouldn’t be able to help you recover them. Note that this will only work for SMS text messages (green bubble conversations), not iMessages (blue bubble conversations). If you’ve deleted a text message that is really critical, you might be able to call your carrier to get a copy of it. Your cell provider might keep a record of text messages you send, at least for awhile. Restore deleted texts by contacting your carrier After a few minutes the deleted text messages should reappear on your iPhone.
Turn off Text Messages (or make sure it’s already turned off). Now go to your iPhone and choose Settings > iCloud. Search the messages to find the ones you need. (If this option isn’t visible, your messages haven’t been backed up here-so you might as well skip to the next method.)
Log into using your Apple ID and password. So try the first two steps to see if you’re one of the lucky ones, and jump ahead to the next method if you’re not. For reasons that remain unclear, in certain territories and for certain phone operators, iCloud simply doesn’t back up SMS messages. It’s called iCloud Merge, but we’ve had mixed reports on how successful it can be. There is a method that’s brilliant if it works, since it doesn’t require a complete reset. Retrieve deleted texts without overwriting your iPhone As long as you haven’t backed up since deleting those text messages, they should now appear in the messaging list on your phone. All the data you previously backed up will now replace the data on your iPhone.
